All about SAP HANA Certification

Last year, SAP introduced HANA based on in-memory technology with which customers can analyze large volumes of data in seconds. This post is about the available certifications on SAP HANA.

As of Feb 2012, SAP has made available only one Associate Consultant certification with code: C_HANAIMP_10. (there are two certifications available now: C_HANAIMP_1 for application consultants and C_HANATEC_1 for technical consultants). C_HANAIMP_1 certification tests knowledge on all aspects of SAP HANA 1.0 for the profile of a SAP HANA Associate Consultant.


The topics in the exam include: Business use cases for HANA platform, loading data into HANA database, modeling and creating views on basic tables to make meaning of the data, creating reports using various tools such as SAP BusinessObjects tools on these created views, optimizing the performance for these reports, user management, security and data access privileges.

Below I have gathered all the information available to the best of my knowledge related to the certification exam:

Q: How many questions are there in the exam?

A: 80

Q: What is the duration of exam?

A: 180 minutes

Q: What are the types of questions asked?

A: As from the sample questions provided by SAP, the questions have single choice or multiple choice answers. Also, as shown in the sample questions, the number of correct answers is indicated for each question.

Q: What is the passing percentage?

A: 59% - which means that you must get all answers correct for at least 48 questions.

Q: If a question has 3 correct answers, and I answer 2 correct answers, will I get partial marks?

A: No. You MUST answer all the correct answers to get marks. The scoring is binary - either you answer a question right or you answer it wrong. Nothing in between. On this note, make sure to pay attention on the indicated number of correct answers to make sure that you have chosen correct number of answers. Choosing less or more answers than indicated will directly get you 0 points irrespective of the correctess of your choices.

Q: What are the available trainings?

A: The following trainings are available and recommended:

1. TZHANA : It’s a 2 day classroom course. Gives a very good overview of all the different components in HANA. The best part about the training was – there were a lot of exercises for the students which gave us a good feel about the overall tool.
2. RHANA : Personally, this is just TZHANA compressed and available in an e-learning format. If you recently did TZHANA you can skip it. Though it’s an awesome way to do a revision of TZHANA (if you did it long time before the exam date).
3. OHA10 : It’s a self paced training; all the material is provided online. Obviously some content overlaps with TZHANA but extra and latest content is available.  I would say this is nice to have (and not a must have) training for passing the certification exam. Of course, I would recommend going through it in the long term.
4. TZH300 : I passed my certification before doing this course, so clearly its not a must have. The course contents includes: how to do transformations using SLT, advanced modeling with HANA Studio, importing-exporting objects, join types, advanced SQL Scripts and CE functions etc.
   
   Please note HA100 will replace TZHANA and HA300 will replace TZH300 in near future.

Q: Which topics are tested in the exam and how is the exam distributed among all the topics?

A: The following tables gives a good idea on where and which topics to focus on (source) . I have added here the approximate number of questions from the percentages given at the certification page.

Topic	% of exam	Approx no. of questions	Primary	Alternative
Business content	<=8%	6	TZHANA, OHA10	RHANA
Data Modeling	>=12%	19	TZHANA, TZH300, OHA10	RHANA
Data Provisioning	>=12%	15	TZHANA, TZH300, OHA10	RHANA
Optimization	>=12%	15	TZHANA, TZH300, OHA10	RHANA
Reporting	>=12%	19	TZHANA, TZH300, OHA10	RHANA
Security and Authorization	<=8%	6	TZHANA, OHA10	RHANA

Q: Is going through the trainings/material enough or do I need hands on experience of data modeling/provisioning?

A: As they say, if you read, you might forget but if you try, you remember for a long long time. Having said that, hands on experience will surely be helpful and is recommended to pass the exam but don’t waste too much time just trying to get access. If you really understand the overall concepts you would have a decent shot in the exam.

Q: How much expertise on BO tools is needed?

A: It’s an exam about HANA and its interaction with BO tools. Expertise on BO tools is not expected, just the overall understanding of the tools and how and when they are useful. To stress my point and not cross any legal boundaries, I will just copy-paste the course content of TZHANA on reporting: SAP HANA Interfaces to BI Client tools, including SAP Business Objects Explorer, SAP Crystal Reports, SAP Business Objects Dashboards and SAP Business Objects Web Intelligence.

Resources:

1. Go to https://www.experiencesaphana.com/ and play around. Go to the “Try” section and spend some time playing with all the “test drives” available. Might not help for the exam but definitely gives an idea of how stuff works.
2. Some really useful videos: Hana Modeler (29 mins, gives very good overview of data modeling in HANA), Demo of Business Objects 4.0 tools consuming data from HANA (13 mins, if you are not used to Information Design Tool (IDT), its a good watch).
3. Training: All HANA related trainings are listed here with sign-up links.
4. If you have access to an HANA system and some extra time, a lot of guides especially for reporting tools are available here: http://help.sap.com/hana_appliance . The best guide to get started on that page is the Modeling Guide, using which you can try out work flows for all aspects of Data Modeling. (Don’t be disappointed with the locked files available only to Partners and Employees; there are many open-to-all guides as well).
5. SAP employees and partners can access the OHA10 course by going to: http://service.sap.com/okp
   If the left hand menu doesn't open automatically, go to: SAP Consultant Education -> Early Product Training -> SAP Online Knowledge Products and search for HANA
6. You can also request access to an HANA system from SAP. All FAQs related to this access are here.

Extra resources (not directly useful for exam, but useful in the long term)

1. Documents: The business case for Hana and a good overview of SAP HANA Architecture.
2. Some very informative documents are available on https://www.experiencesaphana.com/ Go to Browse -> Content -> Documents. Note: the filtering doesn’t work properly, spend some time to find relevant documents.
